ROOFING'.

Application led J'une 30, 1923. Serial No. 648,798.

To all whom it may concer/n:

Be it known that I, JOHN F. TINER a citizen of the United States, residingat gan' Antonio, in the county ofBexar and Statev of Texas, have invented a new and useful Roofing, of which the following is a specification.

This invention relates to-roofing of such4 a nature that it may be used generally in the construction' of buildings, but which, however, is of espeialo value on roofs which are subjected to torsional strains, as in the case of freight cars.

For the last named purpose great ditlil culty is experienced in constructing a roof which is inexpensive, and which'at the same time will stand the wear and strain incident to the careening of the car. The small' pitch of car roofs also increases the difliculty of providing a roof which will not leak.

The objects. of the present invention are to provide a roof which willl be strong and durable, and may be manufactured 'with economy of m-aterial and labor; which is suiiiciently flexible to yield slightly to torsional strains and yet will be leak proof under allconditions, even thoughthe roof is nearly level; and which may be easily applied to the sheathing in proper position and secured there by a single nail.

In carrying out my invention, I have devised a roof constructed from shingles vofspecial design, which arepreferably cut from sheet metal, and so constructed that they maybe .interlocked while being laid, in such a manner as to secure the required degree of flexibility, and yet they will be securely held in such relation to each other that the roof will be leak prooi.

The invention will be better understood 'from the following detailed description taken in connection with the accompanying drawings, which illustrate the invention in its preferred form.

In the drawings:

Figure 1 is a plan view of a blank showing the manner of cutting lthe shingles therefrom without waste.

dll

Figure 2 is a perspective view of a shingle.

m Figure `3 is a fragmentary bottom plan view of a roof constructed in accordance with my invention.

Figure 4 is a fragmentary plan view thereof. Y.

Figure 5 is a vertical section through the roof and part of the sheathing.

The shingles from which the roof is formed are preferably stamped from sheet metal, in the form shown in Figure 2. Each shingle comprises a .rectangular body portion 10 having a shank 11 extending downw-ardly from itslower edge. This shank is half the width of the body portion, and its length is equal to the lap of the shingles after-they are laid. The body portion 10 -is slit, as shown at 12, near each lower corner to provide tongues 13, and a transverse slot 14 is formed 'near the lower end of the shank 11, which when the shingles are laid isy adaptedto receive the adjacent tongues 13 of two shingles in thesubjaeent course.

The manner of laying the shin les is illustrated in Figures 3, 4 and 5. e successive courses are distinguished in Figure 5 by the reference characters a, b, c, d, e, f.,

g and h. The first course. a is made up of shingles in which the shank portion 11 is cut away, while the next course b is laid so as to break joints with the first course, and

with the lower edge of the shank 11 coinciding with the lower'edge of the body portion of the first course, and with the slot 14 receiving the adjacent tongues 13 ofthe two subjacent shingles. The shingles of the twocourses a and bare bent downwardly on the line 16 about the lower edge of the roof sheathing 15 and secured by nails 17 or the like. kThe succeeding courses of shingles` are likewise laid "in a similar manner with each lap equal to the length of the shank 11. Each slot 14 receives -the tongues 13 of the two subjacent shingles so that the successive courses are interlocking, and each shingle is secured byone nail 18 lor the like. Thispermits a certain degree of relative movement between the shingles by reason of the exible connection between the tongues 13 andslots 14.

It is to be noted .that the total length of.

a shingle is equal toa little more than three laps, in' other words, the length of the body portion 10 is a little more than twice the length of the shank portion 11. The shank seen that m kqualities desirable 1n a car roof so as to portion, although it is of less width than the body portion of the shingle, is vheld down in close relation with the subjacent shingles by the tongues 13, and the shingle is just as effective in shedding rain as if the shank extended ythe entire width of the shingle.

The peculiar shape of the shingle with the reduced shank portion not only permits the formation of tongues 13, which cooperate with the slots 14 to interlock the shin-l gles, but also results in a great savingof material when the shingles are cut in the manner indicated in Figure 1,. In this iigure it will be noted that the line 19 separates the two rows of shingles which are cut from the blank, so that the entire width of the blank is only equal to the length of one shingle plus the length of the body portion of another shingle. By cutting the shingles in this manner, the reduced shank portion results in real economy of material since the shingles may be cut without waste.

From the foregoing description it will be invention embodies all the render the same ,ilexible leak proof and durable. It will be understood however that' the speciic structure shown and described is merely illustrative, and that modications may be made therein, aslong as such modifications embody the salient featuresyof the invention as expressed in the appended claims.

What is claimed is:

1. A roofrmade up of interlocking shingles, each shingle having a slit near each lower corner forming a tongue, and having at its lower end a shank portion of less width than the body portion, saidshank portion having a transverse slot in its lower end receiving the adjacent tongues of two shingles in the subjacent course.

2. A roof made up of interlocking shin gles each shingle having a slit near each lower corner forming a tongue, and-having at its lower end a shank portion of less width than the body portion, said shank portion having a transverse slot in its lower end `receiving the adjacent tongues of two yportion extending from the lower end of the rectangular portion between said'slits,

and having a transverse slot in its lower end receiving the adjacent tongues of two shingles in the subjacent course.

4. A shingle comprising a rectangular por tion having two slits at one end near the corners forming tongues, and a shank portion extending from said end of the body portion between said tongues, said shank portion having a transverse slot near its free end capable of receiving the adjacent tongues of two shingles laid side by side in the next course.

5. A shingle comprising a rectangular body portion having two slits extending perpendicularly Jfrom one end near the cor ners thereof and forming tongues, and a shank portion extending from said end ot the body portion and halt as wide as said body portion, whereby two rows of shingles may be cut transversely without waste from a blank as wide as the length of two shingles with the shanks overlapping, said shank portion having a transverse slot near its tree end capable of receiving the adjacent tongues of two shingles laid side by side in the next-course.

-6. A shingle comprising a rectangular body portion having a slit at each lower corner forming tongues, the central part of the body portion being extended down wardly to form a shank ot reduced width, said shank having a transverse slot long enough to receive two adjacent tongues of subjacent shingles.

In testimony that I claim the foregoing as my own, I have hereto afiixed my signature.

JOHN FRANCIS TINER.
